In the general year, the application is given once per generation. The application is repeated once every 7 days in the year in which the major occurrence or the long period occurs. Control rice planthoppers, use 25% microemulsion 100~150ml or 40% emulsifiable oil 50~100ml, add water 70~100 liters, spray to the base of rice, the efficacy period is 7-10 days. Control rice blast, apply in the field of Putian 1 leaf 1 and Honda tiller, use 40% of milk with 200% 250ml, spray on water. Or a 5% granules with a 5% granules 2 to 2. 5 kg. In the prevention of rice weevil, in the peak period, 60 ml of 40% emulsifiable concentrate is used to spray water. (2) Cotton worms on cotton aphid, red spider, blind scorpion, etc., with 30% microemulsion 100~150 ml or 40% emulsifiable oil 50~70 ml, sprayed on water, the efficacy period is up to 7 days.

Control the citrus leaf miner, at the beginning of the shoot, when the shoot grows to 2~3 mm or 50% of the shoots to extract the shoots. Spray with 40% emulsifiable concentrate 1000~1500 times. The peach-proof heartworm is sprayed with 40% emulsifiable concentrate 800-1000 times before the egg-fruit rate is 0.5% to 1%, before the larvae of the first-instar larvae. To control litchi pests, spray with 400% to 1000 times of 40% emulsifiable concentrate, spray the locusts on the lychee and longan 20 days before harvesting, and spray again 1 to 10 days later; The lychee-tip moth is applied when the new shoots of the lychee are extracted and the young leaves begin to unfold; for the litchi scale insects, the application is carried out at the peak of the young pupa. Control orchard termites, spray with 40% emulsifiable concentrate 1500~2000 times. Control cockroaches, use 40% emulsifiable concentrate 60~80 ml, spray on water. (5) Tea tree pests are sprayed on tea mites, tea caterpillars, tea thorn moths, etc. in the larvae of 2 to 3 years old with 1000% to 1300 times of 40% emulsifiable concentrate. Control tea leaves, tea oranges, tea red spiders, etc. before the winter or early spring, if the proliferation of the danger, use 800 ~ 1000 times liquid spray. (6) Soybean heartworm, pea pod, and Spodoptera litura are sprayed with 40% emulsifiable concentrate of 90-120 ml; 2% toxic soil can also be used to apply the surface before the mature larvae enter the soil; or after the harvest of soybeans Apply poisonous soil to kill the larvae. (7) the tobacco pest control tobacco budworm, Spodoptera litura, 40% EC 80 mu to 100 ml of 40 to 60 kg of water spray every 7 to 10 days, spray.
